AUT OMOBILE JACK.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed February 8.1907. Serial No. stassa To all whom it may concern:

Be it known that I, JosE'PH CALVIN MOORE, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain The invention is fully disclosed in the de-- scription and claims following, reference.

being had to the accompanying drawing, in which- Figure 1 is a front elevation of a jack embodying my invention, as in use. Fig. 2 is a central, vertical section of the same in a plane transverse to Fig. 1. p

In the use of an automobile it is possible that as much injury is done to the tires while the machine is at rest as when in action. is, at all events, desirable to relieve the tires from the weight of the machine while at rest in the garage. A jack for this purpose should be adapted for quick action, since it is most conveniently applied to the outer end of the wheel hub, and consequently four are required. It should also be light enough to be easily handled, and at the same time strong and powerful enough for the heavy dutydemanded of it.

Referring now to the drawing, A'is a bifurcated standard with a connecting base B. The legs of the standard are apart sufliciently to take the outer end of a wheel hub, as shown. At the upper end they converge, and between them is pivoted at O a handlever D. The up er' end of this lever is suitably pivoted, as y a E, to a stirrup F,

in ada ted to take the hu as clearly shown inbot figures of the drawing. The stirrup is formed of fiat steel, provided with a series of holes at G for convenience in adjusting it to varying heights of wheel. The semicircular portion of the stirrup is suitably padded, to

prevent marring the wheel hub, in ractice by simply stri ping over it a short piece of rubber hose p In Fig. 2 it will be seen that the legs of the standard are united at I, and this art forms a stop for the bent portion of the and lever when fully depressed. In this osition the line of draft passes a little outside the lever fulcrum, as indicated by the dotted line, so that the jack is self-locked in the supporting position.

In practice the jack is made. of malleable iron, or steel, so as not to be easily broken.

' Notwithstanding its lightness, it is powerful enough to lift the heaviest'wheel by the use of a single hand.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

A jack for automobiles, and the like, comprising a bifurcated standard, a'hand-lever pivoted at its upper end, a cross-piece of the standard forming a stop for said lever when fullydepressed, a stirrup pivoted to the upper end of the lever, and sultably padded, substantially as described. Y a In testimony whereof I aflix my signature in presence-of two witnesses.
